I always wanted a Diatalion figure and finally found one, on eBay, this summer. I'm sorry if it bothers anyone that I modified him but he is now mine, to do so. This takes place, after the Headmaster series, when Cybertron is in its "second golden age". The Autobots are, currently, not fighting with the Decepticons since Scorponok, with Galvatron and gang, are lost out in space. A planet, of only water, (with a submerged "Autobot" symbol) is discovered and the Autobots want to send a team to investigate and explore. Volunteers, are asked for, and Omega Supreme is one of them. It is decided that they would use the, Headmaster, technology to upgrade Omega Supreme and give the Autobots a living/working area and also, some defense, in case the Decepticons return. This first picture is for scale. If Hot Rod and Arcee were to fit inside that control area, they would have to be a lot smaller, so this thing is way bigger than Fortress Maximus. It has the ability to travel through space and to function, underwater. Omega Supreme can connect to it, as the head, and control it in, both, modes but, usually, it is controlled by the Autobots, inside, for the exploration of the planet. Omega connects to the ship in his normal "head mode" spot or he can travel around seperately. I didn't give him an alt mode. He can connect to the body and monitor everything that is going on inside and can scan, for any and all activity, above and below the water surface. The, Omega Supreme, head is still a functioning robot (still as large/larger as he origonally was) but does not have his "Rocket Ship" mode, any longer. I added elbows and knees. I also modified the, small, head. I added the "Neptune" trident for a, handheld, weapon that was reminiscent of Omega's "claw" hand, in combined mode (and because this was a nautical vessel). The Diatalion vehicle still has funtioning electronics but I don't use them since the infared signal from the head, figure, no longer funtions (it only opened up the chest). The battery compartment has a hole cut through it, for Trident storage, but it is still intact. I also cut a hole, in the chest, so a missile could be inserted, and launched, without opening the chest. The, chest, launcher is, still, removeable but cannot be held, by the hands, since the handle is connnected to the Trident. I was going to remove the "Fins" since it didn't work as well with the Alt mode but I like them in Bot mode, since it reminds me of Omega's "tank tracks" as a backpack. I have decide it will be a Holo Imitter and can disquise the ship as, underwater, features or a cloaking device. I did remove the, second, control chamber that was attached to the fin area. I didn't feel it was neccessary. I modified the electronics inside Omega from an infared signal to LED eyes for both heads. The origonal , large head, had an LED in the forehead. I changed it to two small LEDs. Sorry for the picture quaity. Best I could do. The infared signal used to be where the, large heads, mouth is. It is now the push button for the smaller head. I also reversed the small head so it had the opposite side as the chest. The only problem, with doing that, is that the shoulders create a tunnel effect. This pic show how the head would have normally been. Compare it to the one, further, up above. This is the lit up eyes. The head can rotate but it doesn't have any stops, to keep the wires from twisting. This is the only thing that went wrong with this mod. I used a Cybertron Clocker face (for the light pipeing eyes) and when I glued the helmet on, the Superglue fumes left some marks, inside. Only Gradion and Diatalion, from the Webdiver toys, have robot modes but they were made by Takara. I'm surprised that Hasbro didn't do something simular with them. I don't have an official name yet. Maybe Fortress, Omega Supreme or Supreme, Omega Supreme. Let me know what you think.
